So, as a follow up, I emailed the contact listed for Chevrolet yesterday. Contact name is Derek Werner at jackmorton.com Their website states they're a "global brand experience agency", whatever that means.

I said I really didn't want to register as a supplier, and would simply prefer a check as had been done for years. Derek responded quickly and said he had no idea why I would have received that email from IPG, and that I should be receiving my check soon.

Moral of the story, even if an email comes from a "trusted source" that you've dealt with previously (and I do believe it to have been legitimate), question and push back if you don't like what's being presented.
